p *esent invention relates to the machines used for mechanicallyeffecting the g iing of the hinges on the covers of copyboo 's,stitched-books or books, and it has for its ob ect to permit theadaptation of the all the widths of hinges.

it pnrpose, the improvements forming the subject-matter of the inventionare especially characterized by the new application of the press-beltsor press-drums to machines for gluing hinges,- in order to simul--taneously effect, with these press-belts or these press-drums, thedrawing along of the continuous strip from. which the hinges are olna a,and of the covers, and the gluing of the letter on the said hinges.

The accompanying drawing illustrates by way of example only a form ofconstruction of an improved machine for gluing hinges accordance withthe subjectanatter of the invention.

F 1 is a side elevation of the whole of the machine, certain parts ofwhich are omitted for greater clearness.

F 2 is a side elevation of the press-belts which ensure against both thedisplacement of the hinges and of the covers, and their glui Y 3 is acorrespondin planrview.

is a front View of the Whole of the pron v The press-belts used in theexample de scribed are constituted by two belts 1 arranged above asingle belt or endless band 2 held stretched on twodrums 3 the shafts 4of which are suitably supported in the bearings of a frame 5, the upperpart of which constitutes a table 5. The position of these drums 3 isdetermined once for all, but the upper belts 1 are, according to theinvention, mounted on two frames 6 the position in cale, made accordingto lines AA,

height and the spacingapart of which can be adjusted relatively to themiddle longitudinal axis of the table 5*. For that purpose, and asclearlyshown in Figs. 2 and 3, each belt 1 passes between the two sidecheeks of its frame 6 and its lower section passes on rollers 7 -theshafts of which are simply.

' pressed at the bottom of notches provided on the lower edges of thecheeksof the frames 6. The upper section or length of the belt 1 has nocontact whatever with the rollers except the two end rollers 7 and 7',one of which, the roller 7 is a driving roller and receives its movementfrom a mechanism to be here ina' ter described. The frames 6 are mountedby the ends of their, upperpart, on dove tail or like slides 8, so thatthey can be subjected to vertical displacements for allowing theadjustment of the distance betweenthe lower lengths or stretches of thebelts 1 and the upper length of the endless band 2. The slides S-canthemselves slidea'long transverse supporting guides 9 sustainedrelatively to l the table of the machine, by means of brackets 10rigidly secured on the said table. This arrangement allows of adjustingthe spacing apart of the belts 1 and of each of them relav tively to thelongitudinal axis of the endless band 2 0n the table 5 These twoessential adjustments of the belts 1 in the vertical direction and inthe transverse direction, are effected by the operator of the machinefrom the rear end of the table, that is to say from the end where takesplace the entrance of the strips orhinges and of the covers. This resultis obtained by means of the following mechanisms At each of its ends(Fig. 5) a belt-carrying frame receives a member 11' forming a slideblock secured on the frame 6 by means of bolts 12 and provided with aperforated and internally screw threaded boss 13 for engag-V ing with ascrew 14 axially immobilized on the slide 8 by a ring 15 and a bevelpinion 16 pinned at the upper part of the screw 14-. The pinions 16Vrigidly secured on each of the screws 14 arranged at the ends of one andthe same frame 6 gear with corresponding pinionsl? rigidly secured on ashaft 18 journalled in bearings provided upon slides 8, and

the rear end of which is provided with an operating hand-wheel 19 withinreach of the operator of the machine placed at the rear end of thetable. By acting on the handles 19, the operator adjusts at will theheight of the belts 1 above the table and, owing to the arrangement of ascrew 14: at each end of the frame 6, it is possible to obtain verticaland rigorously equal displacements for each of the ends of the frames 6,whatever may be the length of the latter.

An equivalent arrangement is provided for the transverse displacement ofthe slides 8 along the supporting guides 9. On each sup porting guide 9(Figs. 5 and 6) is provided a trough 20 within which is arranged ascrewthreaded rod 21 the axis of which is parallel to the upper face ofthe table of the machine. The rods 21 are immobilized in the axialdirection by a bevel pinion 22 rigidly secured on their outer end and bya shoulder bearing against a boss forming a bearing for supporting therod within the trough-shaped member 20. The bearings are not illustratedin the drawing, as their arrangement is obvious and does not concern theinvention. Each slide 8 is provided with a perforated and internallyscrew threaded boss 23 for engaging with the screw threaded rod 21corresponding to it. The two screws 21 in engagement with the slidescorresponding to one and the same frame 6 are associated by gearing ofthe pinions 22 with similar pinions 23 rigidly secured on one and thesame shaft 24 of the supporting frames 10 and provided, at its rear end,with an operating hand-wheel 26. The four hand-wheels 19 and 26 whichallow to obtain all the adjustments above mentioned, are arranged, asshown in Figs. 1, 2 and 3, at the rear of the machine and the operatorcan easily have access thereto from the latter.

The actuation of the belts 1 is synchronized with that of the endlessband 2, so that the speeds may be rigorously equal if it is desired toavoid the slipping of the hinges and covers they drive along. For thatpurpose, use may be made of the mechanism more particularly shown inFig. 8. The shaft 4 which rotates with the front drum 3 of the endlessband 2 carries at each of its ends, a bevel pinion 27 which, by means ofpinions 28 and 29 and the shaft 30, which is supported by a bearingportion of the table, is connected to a pinion 31 rigidly secured on ashaft 32 connected by a double distortable joint 33, of the Hookes type,to the shaft 34:, driving the roller 7 of one of the belts 1. Theconnection between the elements of the oints is effected by shafts 35and 36 of variable length, constituted by engagement of a rod 36 in atubular part 35 with angular connection by key or claw moving in alongitudinal groove, for always ensuring the transmission whatever maybe the transverse position of the belts 1.

The front drum 3 of the endless band 2 can be directly connected to thesource of power of the machine, or, as illustrated, simply driven by theendless band 2 itself which, in this case, receives its movement fromthe rear drum 3. The latter is connected by pinions 4 and 48 and chain 4for instance, to a driving shaft 37 which receives its movement from anysource of power (not shown).

At the rear end of the table is effected the admission between the belts1 and the endless band 2, of the hinges and covers. The hinges are inthe known manner, cut out from an endless strip 38 (Fig. 1) the edges ofwhich are coated with glue by passage in a gumming device whichpreferably is of the type described in the French Patent No. 652,731,dated January 10th, 1927, for Machine for gluing the backs oncopy-books, stitched-books or books.

The operation of the machine thus described is as follows The belts 1being properly adjusted one relatively to each other, and both of themrelatively to the belt 2, the covers of copybooks to be bound by thestrip 38, are fed from a table 5 (Fig. 1) between the belts 1 and 2. Thefeeding of such covers may be realized either by hand or automaticallyby any suitable means. The pressing action of the belt glues the strip38 to the covers and the whole is drawn to the exit end of the machine.From this end the whole of covers and strip is presented to the actionof cutting means of any arrangement.

What I claim as my invention and desire to secure by Letters Patent is:

In a machine for pasting hinges on the covers of books, a press-beltdevice for simultaneously effecting the feed of the band of hinges andthe pasting of the latter on the for supporting the rolls correspondingto each upper belt, means for moving the said frames both horizontallyand vertically, and means for driving the first roll of each upper belt.

In testimony whereof I have signed my 1:

name to this specification.
